Review of effectiveness and security of blockchain-based solutions based on access control system implementation

This research examines the effectiveness and security of integrating blockchain technology into access control systems (ACS) for university dormitories. Traditional ACS often exhibit centralized vulnerabilities and limited transparency, prompting the need for innovative solutions. A hybrid architecture combining a centralized application with a decentralized blockchain network was designed and implemented using Laravel, React, Go, and PostgreSQL, interfaced with turnstile hardware. Evaluation results indicate that the blockchain-based system achieves high security through immutable logging and decentralized validation, with access checks averaging 0.01 seconds and scalability supporting up to 400 transactions per second. These findings highlight blockchain’s potential to enhance physical security systems, offering a robust alternative to conventional designs.
